Metric O-Rings

QRS offers a large selection of Metric O-Ring sizes in various compounds. A “Metric O-Ring” simply means that the size of the o-ring is defined in millimeters. Generally, metrics are used when the size needed does not cross over to one of the standard AS568 sizes.

While we can supply any material/durometer/color of metric size o-rings, we carry an extensive selection of metric size o-rings in black Nitrile (Buna-N) 70 durometer and Viton (FKM) 75 durometer.
